How many porta potties do you actually need?
Start with your worker or guest count, not a guess. OSHA 1926.51(c) sets construction sites at 1 toilet for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass 20. At 200 or more it drops to one seat and one urinal per 50. If this is a farm crew doing hand labor, OSHA 1928.110 uses a different ratio, one facility per 20 workers, and it has to sit within a quarter mile walk. Events run looser math, more units per guest for shorter, denser crowds. Our porta potty rental cost page breaks down what headcount does to pricing, and if you are still unsure, the how many porta potties do I need guide walks the math step by step. Job site or backyard remodel, check the construction site services page or home renovation porta potty page for use-case specifics before you lock a number.
What size and type of unit do you need?
A standard unit measures about 44 by 48 inches on the ground and stands roughly 92 inches tall, small enough for most yards and job sites in Tempe Junction. If your crew wants a flush and a sink instead of a standard setup, look at the deluxe flushable porta potty. Weddings, festivals and corporate events usually want the step up: a restroom trailer rental, sized as a 2 stall restroom trailer, a 4 stall restroom trailer, or an 8 stall restroom trailer for bigger crowds. ADA Standards section 213.2 requires that at least 5 percent of a cluster of single-user units be accessible, never fewer than one. The ADA accessible porta potty page covers the clearances: ADA 403.5.1 calls for a 36 inch clear route, 404.2.3 wants a 32 inch door opening, and 304.3.1 needs a 60 inch turning circle inside the unit. If the event needs runoff washing after using paints or coatings, that is OSHA 1926.51(f)(1), a different rule than everyday sanitation.
Where should the units go on your site?
Placement decides how smooth delivery day goes. A roll-off or trailer delivery needs about 60 feet of straight clearance behind the truck, so measure your driveway or lot access before delivery day, not during it. Keep units on stable, level ground; ADA 302.1 requires slip resistant, firm surfaces for any accessible unit, and a ramp, if you need one, cannot run steeper than 1:12 under ADA 405.2. Placement in the public right of way needs confirming with the City of Tempe Junction directly; we cannot state a blanket rule here, so check with the city before you plan units on a sidewalk or street shoulder. The porta potty placement guide has more on spacing and truck access, and the porta potty permit requirements page covers what else the city might ask for. If you are running a job site with a roll-off dumpster too, coordinate both deliveries; see roll-off dumpster rental and dumpster permit requirements for that side of the checklist. Sites 3.5 miles southwest toward Guadalupe or 15.8 miles north near Paradise Valley follow the same placement logic, just confirm locally.
When should you schedule service and pickup?
Service interval matters as much as unit count. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users over a 40 hour week, so a busy job site or weekend event needs more frequent pumps, not the standard schedule. Book delivery a few days ahead if you can; a porta potty rental per day order is easy to arrange fast, but a monthly porta potty rental needs more lead time for the vendor to route the truck. Weekend events in Tempe Junction often run at a premium over a weekday rate, so ask about that when you book. If you are also renting a handwashing station rental or portable sink rental, 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at any handwash station, sanitizer alone does not satisfy it. Plan pickup for the day after your event or the day your permit or job wraps, and confirm it in writing. For anything urgent, the emergency porta potty rental page covers same-day options.
| unit | duration | typical price |
|---|---|---|
| standard | day | 150 |
| standard | week | 200 |
| standard | month | 200 |
| ada | day | 230 |
| deluxe | week | 250 |
Do I need a permit for a porta potty in Tempe Junction?
It depends on where the unit sits. Placement on private property usually needs no city sign-off, but anything touching a sidewalk, street or right of way needs confirming with the City of Tempe Junction. Check the porta potty permit requirements page before delivery day.
How often are porta potties cleaned?
Industry baseline under ANSI/PSAI Z4.3 is once a week for up to 10 users over a 40 hour week. Busier sites or events need more frequent service. See how often are porta potties cleaned for scheduling detail.
What is the difference between a standard and deluxe unit?
A standard unit is a basic 60 to 70 gallon holding tank unit, no sink or flush. A deluxe unit adds a flush mechanism and handwash sink. Compare both on the standard porta potty rental and deluxe flushable porta potty pages.
Can I rent just one unit for a small backyard project?
Yes. A single standard unit covers most home renovation and small backyard jobs. Check the home renovation porta potty page or porta john rental for single-unit options and delivery details.
How far in advance should I book?
Book standard daily or weekend rentals a few days out. Monthly job site rentals and large events need more lead time to route delivery trucks. Start with request a quote to lock your date early.
